AWNING PULLEY OR SHEAVE.

SPECIFICATION forming part of Letters Patent No. 792,357, dated June 13, 1905.

Application filed October 11, 1904. Serial No. 228,016-

To all whom, it may concern:

Be it known that we, THoMAs B. SMITH and HUMPHREY IV. -FONTAINE, citizens of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a certain new and useful Improvement in Awning Pulleys or Sheaves, of which the following is a specification.

ur invention relates to a new and useful improvement in awning pulleys or sheaves, and has for its object to provide an awning pulley or sheave which will guide the rope as it extends from the pulley to the frame of the awning, so as to prevent the material catching in between the pulley and the rope when the awning is raised.

With these ends in view this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will now be described in detail, referring to the accompanying drawings, forming a part of this specification, in whieh- Figure 1 is a front elevation of our improved pulley; Fig. 2, a side elevation of the same; Fig. 3, a vertical sectional view through an awning, showing our improvement in use; Fig. 4, a side elevation of a portion of the pulley-frame, showing the same pivoted with a ball-and-socket joint; Fig. 5, a front elevation of the bearing shown in Fig. 4 with the ball in place; Fig. 6, an under side plan view of Fig. 5.

It is a well-known fact that when awnings are raised and the material of the awning becomes slack and begins to fall said material is very apt to be drawn in between the pulley and the rope, and as the rope continues to be drawn upon the material will be drawn farther in and be torn by the sharp edges of the pulley. Our invention is for the purpose of obviating this, which we do by providing a guide for the rope leading from the pulley to the frame of the awning.

A represents the pulley or sheave. I

B is the frame, which consists of two ears B, between which the pulley or sheave is journaled'.

C is the plate, adapted to be secured to the building or window-frame, and this plate is provided with two ears 0, between which a lug extending from the frame B is pivoted.

D is a tubular guide extending from the frame B at an angle, as shown in Fig. 2, the angle being substantially the same as that of the awning. The rope E after passing over the pulley A passes through the guide D down to the awning-frame. Thus the material of the awning in folding will strike the top of the guide, and this guide will prevent said material from coming in contact with the pulley or rope at the point where any damage can be done.

In Figs. 4, 5, and 6 we have shown a modified form of construction, in which the frame B instead of being simply pivoted on abolt is universally pivoted, so that it may turn in any direction and follow the rope no matter in which way it is pulled. In this construction the ears C are provided with cavities upon their inner faces, and the plate C is made in two parts, so that it may be separated by the ears C, and the frame Bis provided with an extension F, having a ball F upon the end thereof. This ball F is adapted to lie between the ears C and rest within the cavities within said ears, thus forming a ball-andsocket joint. The advantage of making the device with a hall-and-socket joint is that this one form of device would answer for all forms of awning-pulleys. In simple window-awnings the pulley need not be universally jointed, as then it is only necessary that the frame shall be pivoted to rock in a vertical plane; but in store-awnings, where the awning is raised by a rope at one side, it is necessary that the ropes run horizontally along the top of the pulley from one side to the other, and therefore said pulleys must be able to turn to accommmodate themselves to the run of the rope.

Of course we do not wish to be limited to the exact construction here shown, as slight modifications could be made without departing from the spirit of our invention.

Having thus fully described our invention, what we claim as new and useful is 1. In an awning pulley or sheave, a grooved pulley, a frame in which the pulley is journaled, a plate by which the pulley is secured in place, the frame being pivoted to said plate, a tubular guide formed integral with said frame and extending from one side thereof at an angle downward through which the rope is adapted to pass from the pulley to the awning-frame, as and for the purpose specified.

2. In a device of the character described, a grooved pulley, a frame in which the pulley is journaled, a plate by which the pulley may be secured in place, ears extending outward from said plate, an extension formed upon the frame, said extension being pivoted between the ears of the plate, a tubular guide extending from the frame at an angle from the opposite side of the frame to that pivoted to the plate, the rope from the pulley adapted to pass through said tubular guide to the awning-frame, as specified.

3. In a device of the character described, a grooved pulley, a frame straddling said pulley and forming a bearing therefor, a plate by Which the device is secured in place, ears extending outward from said plate, an extension extending from the upper end of theframe, a ball secured upon the outer end of said extension and adapted to lie between the ears of the plate so as to form a ball-and-socket joint, a tubular guide extending from the frame at an angle, and rope adapted to pass over the pulley and through said tubular guide to the frame of the awning, as specified.

In testimony whereof We have hereunto affixed our signatures in the presence of two subscribing Witnesses.
